Maritime and

Offshore design

BETA CAE Systems software suite offers simulation solutions that cover the advanced needs of the Maritime industry. The advanced pre- and post- processing capabilities of our suite, will greatly contribute to costs reduction during your research and design processes, while the abundance of tools and practices will help you take your simulation analyses to new levels and grasp the behavior of your models in trials for the sea.

Perform your Maritime simulationin a single environment which offers all the tools you need

Model set up

- Integrated CAD tools for geometry creation, modifica-tion, cleanup and defeaturing.

- Middle skin extraction for complex parts with fully auto-matic functionality that produces high quality mesh and assigns nodal thickness.

- Powerful Batch Meshing that respects the user specified quality criteria and mesh parameters. Among others, ANSA offers automatic feature recognition and defea-turing, special treatment for fillets, flanges, tubes and holes, different meshing sessions for different areas of the model, local refinement and coarsening.

- Fully automatic curvature dependent surface meshing with user controlled growth rate, min & max element size and mesh feature angle.

- Fast and robust volume meshing for tetra, prism, pyra-mid, hexa and polyhedral elements.

- Generation of smooth boundary layers, advanced control for squeezing, collapsing or excluding to overcome quali-ty and proximity issues.

- Automatic creation of beam elements with cross section selected from a user generated database. Replacement of meshed parts with beams of the same cross section.

- Distribution of non-structural mass for the proper total weight distribution.

- A variety of options for boundary conditions definition.- Interoperable pre-processing decks for numerous

solvers for FEA and CFD analyses.- Automatic “Rigidize” feature for the replacement of a

model part by rigid bodies that contain the mass and iner-tia of the substituted areas.

- Substructuring function to define an area of interest on the full body, while preserving loadcase attributes of the original loadcase setup.

- Parametric shaping of both FE model and geometry through the use of Morphing Tool, with model validation through the animation of model shaping, using the Simu-late tool.

- Enhanced Design of Experiments, full factorial algorithm for easy definition of experiments.

- Direct coupling of ANSA and META with the most com-mon parametric optimizers.

- Map pressure or temperature results from a CFD simula-tion to a FEA model.

- Easy creation of Smoothed-Particle Hydrodynamics (SPH) inside a volume of any shape.

- Creation, manipulation and calculation of cross sections using the Cross Section tool.

- Calculation of liquids level inside a tank of any shape, us-ing the Tank tool.

- Calculation of ships & offshore platforms displacement and of corresponding waterline.

- Sinusoidal and Trochoidal waves with user specified pa-rameters.

- Calculation of ships & offshore platforms static position, considered momentarily balanced upon a design wave.

- The Task Manager tool organizes a stepwise sequence procedure that manages all steps and actions necessary for the model build up.

- A C-like scripting programming language automates ANSA procedures. An easy way to perform repeated ac-tions, to manipulate all entities and drive most of the core functionality.

Post-processing

- Hot spots identification through filtering capabilities in-corporated in many tools of META.

- Overview of results achieved through statistics tables with spreadsheet functionality.

- Integrated calculator for linear combination of results de-riving from other loadcases. New datasets can be cre-ated by applying any mathematical operation on existing data.

- Calculation of forces and moments on any user defined section and output in solver format to be used for sub-modeling.

- Integrated powerful graph tool for direct plotting of data deriving from the 3D model or from imported solver time history files.

- NVH post processing with a whole variety of 2D plots and integrated tools like modal model building, modal re-sponse calculator and FRF assembly.

- Post-processing for durability and fatigue analysis is greatly assisted by parameterized sessions and scripts.

- Coupling of META with external optimizers achieved through an integrated toolbar.

- Support of CFD results format such as ANSYS FLUENT and OpenFOAM. Streamlines as lines, ribbons or cylin-ders and colored by any available variable.

- Image matching and video synchronization for results validation.

- Reports creation in html, Postscript or pptx format using the Report Composer.

- Dragging and dropping images and copy to clipboard functionality for transferring data.

- Customized toolbars creation through the toolbar de-signer.
